above, extends down through the casing and transmits power to the rotary pumping means below. The means for supporting said rotary pump and the long power shaft in-- volves considerable inconvenience. In some pumping systems the rotary pumping parts and power shaft are partly supportedfrom below by means of a delicate hydraulic bearing located at the bottom of the casing, and said hydraulic'bearin-g is operated by the same water pumped through the well. This construction, however, is subject tothe' following inherent defects: The bearihg, being operatedby well water, which obviously carries some sand and grit from its origin,

soon rusts and wears, andits operation be- .comes quite unsatisfactory.- Also said delicate hydraulic bearing, being located at the bottom of the well-casing, is practically inaccessible; and due to the frequent repairs' required-on same, its up keep" involves considera'ble annual expense.

no pressure head at the level of the bearing, and from a practical standpoint would therefore'be incapable of producing an upward reaction sufficiently adequate to support or floata long suspended shaft and impeller. Such bearings must therefore be located at some point down on the shaft and access to them is consequently difficult. The higher up such bearings are placed the more cumbersome and large must be their construction, because they must support a definite weight and at higher levels have less fluid head with which to do it; while when such bearings are placed lower down and close to the well pump they become very inaccessible, and the rattling and buckling tendency of that portion of the shaft above the bearings becomes'pronounced and detrimental. Putting such a bearing down close to the pump, however, sometimes makes it possible to use a reasonably small and convenient bearing, and in practice this position is therefore the most practical despite the difficulty of access.

The invention includesa novelly-construct- "ed 'fluid operated bearing novelly located at the top of the long power shaft which exsource separate from the main well pump it self, and on this account it is possible to locate the bearing practically atthe top. of the shaft and immediately at or reasonably near 'tolthe surface of the earth. This position makes it perfectly accessible to repairs and makes it possible to suspend practically the whole length of the shaft. All rattling and buckling of the shaft is thereby eliminated-and the installation runs smoothly and practically without vibration.

tends-downto andoperates the pump. The

of'the bearing means embraced inmy invention is to reduce the friction created by supporting the rotary pumping parts and the vertical power shaft. To this end I provide the novel fluid operated hearing hereinafter described.

Another object is to provide durable and eflicient bearing means for supporting the vertical power shaft and the rotary pumpparts, which hearing shall be easily and-convenientlyaccessible ate-the surfaceof'. the earth. To this end I provide above the pit casing, and near the upper extremity of the power transmitting. shaft, a novelly constructed hearing which may be readily dismantled for inspection and repairs. As will be hereinafter described the vertical power shaft and the rotary pumping means are suspended from the bearing, and the buckling and weakening tendency of said power shaft is thereby obviated. Also the relatively long and usually rapidly rotating power shafts embraced in this invention will. not abuse the bearings which may give it lateral support along its length, because this invention contemplates particularly that the shaft shall-practically depend from the fluid bearing located near its upper extremity so that the weight of the'shaft draws it into a substantially straight vertical line instead of permitting it to buckle onto its bearings when partly supported from below. Another objectis to avoid excessive wearing and rusting of the bearing parts and at the same time to efficiently lubricate the same. To this end I use lubricating oil under pressure for operating the novel fluid bearing hereinafter described.

Other objects may appear from the following detail description taken in connection with the drawings.

The following drawings illustrate my invention. l

Fig. 7 is an axial section of the same parts shown in Fig. Fig. 8 is a fragmental view illustrating the well mechanism in place and broadly shows the novel combination of parts embracing my invention. Fig. 9 is a plan View of one of the bearing castings.

Into the earth 1 is sunk a cylindrical drum 2 shown in Fig. 8 and termed a pit casing; At the lower extremity of pit casing 2 the coupling member 3 connects said pit casing to ,a well casing 4, said we'll casing having a lower screened and perforated portion 5;

and at the upper extremity of saidpit casing the flange plate 6 connects said pit casing to a discharge Y 7. The well casing 4 projects down into the water bearing sands andgravels and is adapted to form a well reservoir from which the rotary pumping means 8, located in pit casing 2, and usually near the bottom thereof, may draw its water supply.

The pumping means 8 comprises a stationary pumping casing 9 and a rotary impeller 10, both of which are conventionally shown and represent casings and impellers of any variety whatsoever. At its lower end the pump casing 9 is connected with a suction pipe 11 extending into the well casing 4 and being adapted to conduct water up to the pump casing; and at its upper end said pump casing is connected to a water conduit 1-2, the latter serving to conduct the pumped water up to the discharge Y 7. This water conduit 12 is rigidly connected to the discharge Y above, and in an obvious manner serves to support the pump casing 9 and the suction pipe 11 in their operative positions. The impeller or rotary pumping parts 10 may be connected in any suitable manner to the long power shaft 13 which extends down through the pit casing 2 and which is driven from above by means of a pulley'14. A small pipe 15 supported as hereinafter described surrounds power shaft 13 and is adapted to contain an oil bath wherein said power shaft runs. The weight of the impeller and of the'long power shaft are novelly supported and suspended at the surface of the earth in a novelly constructed and novelly positioned fluid operated bearing 16, the details of which will be described below. When the power shaft 13 is driven the pump impeller 10 will rotate and by means of the suction pipe 11 water will be drawn from the well casing 4 into the pump casing 9. On continued driving of shaft 13 the rotary impeller 10 will force this water up through the conduit 12 and dischargeit through the discharge Y7. It will be understood that part of the weight or downward re-action of the water in conduit 12 is sustained on the impeller 10, and must be added to the weights of said impeller and power shaft 13 in considering the total weight supported above in bearing 16. The details of this bearing will now be described.

The upper face of the discharge Y 7 ,Fig. 1,'is formed with two ofl'set seats 17 and 18 joined by the shoulder 19, and by means of bolts 20 the similarly but conversely formed face 21 of the casting 22 is securely attached to the discharge Y. From the lower face of casting 22 depends a cylindrical portion 23 which loosely surrounds the power shaft 13 and forms about same the packing chamber 24 containing the packing 25. The usual packing gland 26 extends into the packing chamber 24 and is secured to and adjusted on casting 22 by means of bolts 27. The lower extremity of the depending cylindrical portion 23 is provided with threads 28 upon which is secured a similarly threaded coupling 29. The upper extremity of oil-containing pipe 15 is seen to be similarly threaded also, Fig. 1, and by screwing same into coupling 29 a complete and adequate support for said pipe is provided. The casting 22 terminates above in a flange 30, from the lower face of which depends another cylindrical portion 31 which embraces ower shaft 13 so as to form another packmg chamber 32 containing pacln'ng 33. The usual packin gland 34 extends into chamber 32 and ls secured to and adjusted on cylindrical portion 31 by means of bolts 35. In order that the aforesaid packing glands and bolts may be accessible for inspection and adjustment two hand holes 36 are provided in opposite sides of the casting 2 2. The flange '30 is thickened at one side so as to provide suflicient metal through which the horizontal fluid conduit 37 may pass. At its outer extremity said conduit is provided with threads 38 and at its inner extremity said conduit joins the vertical conduit 39, the latter extending up through a cylindrical projection 40, Figs. 1 and 9, which rises from flange 30. The periphery of the projection 40 is threaded as at 41 and a similarly threaded wear plate 42 is screwed upon same. A screw 43 looks wear plate 42 to projection 40 and an ordinary rlng slot 44, ig. 7 permits a packing ring 45 to be sprung around the periphery of wear plate 42. v

Above projection 40 and wear plate 42, and spaced apart from same, is positioned a balancing plate 46 having a depending inachined rim 4'} which coiiperates with the packing ring 45, with wear plate 42, and with projection 40, to form the substantially fluid tight chamber 48. The balancing plate 46 rotates with the power shaft 13 and is. firmly and rigidly attached to same by means of keys 49 lying in key slots 50 and 51 in the power shaft and. balancing plate respectively and fitting snugly between the slot shoulders 50 and 50" in. the shaft. The keys 49 extend abovethe balancing plate so that they slots 51. With this construction it becomes necessary, however, to bind the upper portions of said keys tight into the slots 50 of shaft 13; and for this purpose I provide a split collar comprising two removable seg- -ments 52 and 53 best shown in Fig. 3. The segments of this split collar embrace the keys 49 and when in position serve to bind them tightly into the aforesaid slots. The periphery of the segments 52 and 53 is provided with screw-threads 54, Figs. 4 and 5, and a similarly threaded annular collar 55 is screwed onto segments 52 and 53 and serves to rigidly hold them in position. The

set screw 56 is also provided and sets the collar 55 firmly onto segment 52. By this mav be readily withdrawn from.

construction balancing plate 46. may be easily and rapidly disconnected from the power shaft 13, and is also rigidly connect-3 ed with said shaft in such manner that all the weight carried by the shaft may be imparted to and sustained by the balancing plate 46.

It will be seenthat the fluid tight chamber 48 is bounded above by the balancing plate 46 and is connected below throughconduittight chamber 48 where its pressure will act upwardly on balancing plate 46. If the fluid pressure in said chamber is correctl chosen its upward eflort on the balancing plate 46 will balance all the high pressure through pipe 59 into the fluid T weight of shaft 13 and the parts supported by same. In this condition the power shaft is said to float, and its weight-will be suspended from or supported on the upper surface of the fluid in chamber 48. As the shaft rotates in this floating. condition the, supporting friction of same will be slight and ,will include only the" resistance between the supporting fluid surface and the balancing plate 46, and between the packing ring 45 and the'rin'g slot 44. The, shaft 13 often runs approximately at 1000 revolutions per minute and supports a total weight of 2000 pounds or more; and I have found thatunder these conditions suspension from a fluidsurface is essential if durability and efiiciency are to be attained. It might seem to be a preferred mode of operation to have the shaft always suspended in a floating condition, but in practice several efl'ects conspire .and make constant floating difficult.

fluid pressure in chamber 48 is sometimeseither superfluous or deficient, so that a summation of shaft forces, including the fluid pressure on the balancing plate, the shaft The weight, the impeller weight and. the water weight will leave a resultant upward or" downward force of the shaft. Safety valve 58 is of ordinary conventional construction and-tends to prevent any surplus fluid pressure on the balancing plate 46, the safety valve operating to release a portion of the I fluid acting on the balancing plate and thereby eradicating the surplus pressure referred to. The fluid released by the safety valve will drop -into the oil sump beneath,

thereby preventing any waste ;of same. As

a safeguard, however, against failure of the safety Valve 58 I provide auxiliary bearing means adapted to sustain any resultant upward force of the shaft, said upward force being occasioned by surplus fluid pressure on the balancing platei46. This auxiliary bearing means is located directly above collar 55 and comprises the following parts: A circular ball race 64' is cut in the upper surface of collar 55, and a series of hard steel anti-friction balls 65 are adapted to run in the same. spaced apart from same, is another ball race 66 cut in a wear plate 67. Wear plate 67 is attached by screws 68 to a neck 69 depending from a casting generally referred to as 70, the said casting being rigidly s ecured at its lower end to casting 22 by means of bolts 71. By providing this auxiliary bearing means the objection to superfluous fluid pressure in chamber 48 is overcome, be cause the resultant upward shaft force will be adequately sustained by the anti-friction balls 65 and wear plate 67.

The upper face of flange is formed with two offset seats 72 and 73 joined by the vertical shoulder 74, and the lower face of flange 75, of casting 70, is formed with both similar but conversely offset seats. The offset seats 17 and 18 on the discharge Y 7 and casting-22, and also the offset seats 72 and 73 of the castings 22 and 70, serve to maintain the discharge Y and the castings 22 and in perfect alinement, and additionally serve to provide fluid tight joint between said elements. Above flange 75 the casting 70 is built with a cylindrical portion 76 which forms a second chamber 77 surrounding and including both the fluid tight chamber 48 and the auxiliary bearing means above referred to.

Under normal operation fluid will slowly leak from the chamber 48 past the packing ring 45 into the chamber 77. There being no escape for this fluid from the lower part of chamber 77 the same will gradually fill said chamber until the whole of the balancing plate and also the balls 65 of the auxiliary means will be immersed. An overflow pipe 78 taps chamber 77 above the auxiliary bearmg means and serves to conduct. the fluid from chamber 77 back to sump 62 when said fluid rises above the level of said overflow pipe. For purposes of clearness, however, theoperating fluid has been omitted from chamber 77.

By choosing clean oil as the fluid for operating my bearing, no sand or grit will be injected between the active parts and a good wearing capacity will be thereby procured. Also there will be no rusting tendency of the bearing parts and the delays and danger introduced by rusted metal will be avoided. Also the whole of the fluid bearing and the auxiliary bearing means being immersed in the oil, an efficient and adequate lubrication Above said balls, and

will always exist at every friction point. Also by providing overflow pipe 78 no oil is wasted and economy of operation is a prominent feature in my installation.

As a safeguard against pressure deficiency of the fluid in chamber 48 I provide a second auxiliary bearing means located within the cylindrical portion 79 of casting 70. A web 80 extends across casting 70 between the cylindrical portions 76 and 79 and from said web rises a boss 80. An enlarged aperture 81 is provided in said boss and permits power shaft 13 to pass through same, the said aperture being flared into an upper concave seat 82. Into aperture 81 and concave seat 82 fits an appropriately shaped casting 83, the same having a projecting drum 84 and a central aperture 85, the lat ter being adapted to loosely embrace power shaft 13. A circular disk casting 86 is formed with an inclined wheel race 88 extending in a circle completely around said casting. From the bottom of casting 86 depend two lugs 89 positioned so as to interfere with corresponding lugs 90 rising from web 80 of casting 86. The lugs 89 and 90 cooperate to arrestand prevent rotation of casting 86 and casting 83 around shaft 13. A cast annular frame 91 carrier three inclined anti-friction wheels 92, Figs. 1 and 2, said anti-friction wheels being journaled to the frame by means of pins 98, and said wheels being adapted to run in the wheel race 88. The cast frame 91 is provided with an aperture 94 and within said aperture is positioned a casting 95 having a. lower inclined face 96 adapted to rest and roll upon the inclined anti-friction wheels 92. The

power shaft 13 is threaded above at 97, and v lar 98 isscrewed home, casting 95 and shaft 13 are bound to each other. When there is a pressure deficiency on balancing plate 46 a resultant downward force exists on power shaft 13. This force is transmitted to casting 95 and from same is passed to and sustained on the auxiliary bearing means comprising anti-friction wheels 92 and cast ring 95. As shaft 13 and casting 95 rotate the wheels 92 will roll around the wheel race 88 and due to the relative radial distances of inclined face 96, and inclined wheel race 88 from the center of shaft 13, the cast frame 91 will rotate at a slow speed compared with that of the shaft 13 or casting 95. By this construction the friction necessary to support the rotating shaft is negligible, despite the resultant downward force ofsame.

At the upper extremity, shaft 13 is pro.- vided with a belt pulley 14 rigidly mounted -on the shaft by any suitable means such as the square thread 100, and power is imparted to same by any ordinary belt as will be readily understood.

All of the above described construction discloses in detail one form of mechanism whereby the benefits of this invention may be secured. It will be understood, though, that many of these details may be varied very extensively without departing from the spirit of this invention as claimed below. Thus, this inventionis not avoided by using any other suitable form of fluid operated bearing whatever, so long as it is located substantially at the top of the relatively long power shaft so that the shaft practically depends from the bearing and by its own weight tendsto draw itselfinto a substantially straight vertical line. Though itis preferable also to use auxiliary or supple mentary bearing means for the purpose of supporting any upward or downward thrusts on the power shaft, nevertheless an operative structure is produced without any of these supplementary bearing means, and this structure is also included in this present invention. This being so, it is, of course, understood that the auxiliary bearings may take any form whatsoever without regard to the above described details which show only one form of the invention.

In starting the well mechaaiism'embracing this invention the pumping means 60 is brought into operation to raise the oil pressure in chamber 4.8 until the vertical weights or forces on shaft 13 are balanced and said shaft floats on the oil surface. Power is then imparted to pulley 14 and is transmitted by shaft 13 to the impeller 10 which effects the pumping and discharging of the water through discharge Y 7. If for any reason a surplus or deficient oil pressure exists on the balancing plate, the auxiliary.

bearing means located either within the cylindrical portion 76 or the cylindrical portion 79, of casting 70,- will operate to sustain the resultant force of the shaft.

The provision of the auxiliary bearing means for sustaining any resultant downward force ofthe shaft over and above the force counterbalanced by the fluid bearing, is very important in pump installations for the following reason: The installation is usually driven directly or indirectly either by an electrical motor, a gas engine or other source of motive power. The speed variations of the prime mover are minimized as .much as possible considering the practical conditions of operation but there may, however, be some speed variations due to voltage changes when the electric motor is used or to changes in the quality of the gas when a gas engine is used, .and these variations are, of course, beyond the control of the operator.

If the speed of the shaft goes up the rotary speed of the impeller would also go up and thrust of the long power shaft would also.

change due to .the changing reaction of the long column of water on the impeller. These velocity .changes and the corresponding thrust changes may, witht, certain types of impellers, become so considerable as to be serious, and are a gravated somewhat by the torsional coil an recoil of thelong shaft. It being impossible from a practical standpoint to vary the pressure of the fluid hearing in accordance with the velocity changes and corresponding thrust changes of the shaft, it becomes advantageous to provide the supplementary bearing means for supporting the resultant downward thrust on the shaft. In this event, the fluid pressure on the fluid hearing may be set for the nor but the resultant downward thrust is taken up by the supplementary bearing in casing 79.

The above described reaction of the water column is most noticeable with impellers whiclrwork'partly on a screw principle so as to directly push the water upward. It should also be noticed however that various other distributions of the total shaft thrust between the fluid operated bearing and the supplemental bearing can readily be made. For instance, the pressure in the fluid hearing may be kept at a slightly lower value than that supposed above so that the shaft is always supported somewhat by the supplementary bearing. In this event the shaft will certainly not have any upward or downtary bearing, this latter portion of the,

weight also serving to hold the shaft steady despite pressure fluctuations in the fluld' bearing. Though the supplementarybearing may be located at any referred-or desired point, it is a further a vantage to have it also located near the" top of the shaft and in reasonably close pro-xlmity to the fluid operated bearing. In this event the long and heavy power shaft depends from both bearings and by its own weight tends to i draw itself into-a substantially straight verv ported from below.

tical line. Such location of the bearing means not only makes the same very accessible for repair and adjustment but also implrloves the performance of the shaft materia y.

If at any time the bearing is to be dismantled for repairs the bolts 71 and the pulley 14 are removed, so that the casting may be raised off casting 22 to display the bearing elements beneath. The bearing being located at the surface of the earth readily accessible for this purpose and, together with the rapidity by which same may. be dismantled, a substantial advance in the art is effected. Furthermore, it is a wellknown fact that the power-transmitting capacity of shafts under compression is less than the power-transmitting capacity of shafts under tension. By supporting or suspending the heavy power shaft and pumping impeller from above, and thereby operating said shaft under tension, my invention permits a more complete utilization of the power-transmitting capacity of shaft 13 than is possible in the constructions where the shaft and pumping impeller are sup- Also, with this arrangement all buckling and bending tend ency of the shaft 13, along with its consequent vibratory and rattling tendency, are obviated.

Attention will now be called to another feature ofthe invention. As has been above described, the auxiliary bearing in casing 79 includes the boss 80 having the concave seat 82, for supporting the appropriately-shaped bearing casting 83, while by reference to Figs. 1 and 7, it will be seen that the fluid operated bearing has a certain amount of play and clearance both between the depending rim 47 and plate 42, and between the balancing plate 46 and plate 42. Before stating the several purposes of this construction, it may be noticed, however, that in practice the actual play between the depending rim 47 andthe plate 42 is not so great as v has been-illustrated in Figs. 1 and 7 and, in

fact, is usually so small that it would be im'- possible for the figures to show it if it were drawn in correct relative proportion to the remainder of the mechanism. -In practice, this play need only be as great as would be encountered in a very loose bearing fit, but for the purpose of bringing it out, this has been considerably exaggerated in Figs. 1 and 7. These features in the auxiliary bearing and in the fluid operated bearing are introduced so that the bearings may accommodate themselves to the shaft as the axis of the latter may from time to time tend toswing or shift around in the bearings with a pendulum action. It is quite essential to the perfect performance of a bearing systemat the top of long pump shafts that such swinging reactions should be allowed for, because the shaft 13 penetrating deep into the earth may have its lower end pushed around con siderably by the ununiform sliding or settling of the various layers of earth through which the shaft passes. On this account, t e sand approximately in the region of the pump may shift the latter,.-and, therefore, the lower extremity of'the shaft-so-mewhat to the side. The shaft being rigidly connected to the balancing plate in the fluid operated bearing, will, therefore, carry this bearing plate over sidewise and'unless the above-referred to play were allowed in the fluid operated bearing the latter would force its parts together unusually hard so as to wear them fast, while the fluid operated bearing would also hold the upper extremity of the shaft in a flexed and strained posit-i on with reference to the lower parts of the shaft. By the play shown in Fig. 7, however, all this is avoided so that the fluid op-- erated hearing may readily accommodate itself to the shifts which are incident to the axes of all pump shafts. This problem has been previously solved for roller bearings such as shown in the applicants casting 70 when such roller bearings were used alone, and the appropriately-shaped casting 83 ridinginthe concave seat 82 has always been understood by practical well men to be for the purpose of allowing the roller bearing to accommodate itself to such swinging of the pump shaft, so that this feature need, there fore, not be further described, with reference to the roller bearing.
